Unit Test Atomic Structure and Radioactivity

Today we took the unit test, and although it took me the whole class period to finish, I did not feel like it was as difficult as I expected. Last night I reviewed alpha and beta decay as well as half life equation, and I am glad I did because I noticed many question were on these subjects. I noticed there were many questions about alpha decay in particular. Overall this unit test went smoothly, and I did not need to stress as much as I did beforehand.
